Small Fermi Surfaces and Strong Correlation Effects in Dirac Materials with Holography
Recent discovery of transport anomaly in graphene demonstrated that a system
known to be weakly interacting may become strongly correlated if system
parameter(s) can be tuned such that fermi surface is sufficiently small. We
study the strong correlation effects in the transport coefficients of Dirac
materials doped with magnetic impurity under the magnetic field using
holographic method. The experimental data of magneto-conductivity are well fit
by our theory, however, not much data are available for other transports of
Dirac material in such regime. Therefore, our results on heat
transport,thermo-electric power and Nernst coefficients are left as predictions
of holographic theory for generic Dirac materials in the vicinity of charge
neutral point with possible surface gap. We give detailed look over each
magneto-transport observable and 3Dplots to guide future experiments.Comment: 32 pages, 24 figure
